If you let an AI do the scoring, start by doubting the scores

When I had an AI score quality, just measuring the same thing twice moved the number by 6 points. The "+7-point improvement" that wobble produced turned out to be a dead heat head-to-head. Calibrate the judge itself first, or your improvements are chasing illusions.


That "accuracy" is a definition you chose

When you say "improve accuracy," that "accuracy" is nothing more than a definition someone chose. Optimize against a judge that only returns pass or fail, and the value that definition doesn't capture is the one thing left behind, flat. The ceiling on improvement isn't the model — it's the impoverished definition.


Don't explain the "why" until you've taken a control

The number moved, it got better, here's the mechanism — you'll want to say all of it. Before you do, take one control (a comparison that differs from the treatment in the one factor you're testing and is matched on everything else). If a cheap control beats an expensive change on every axis, that change added nothing. What looked like an improvement was confounding.

Testing an MCP server at the stdio boundary: handshake, discovery, and real calls

Unit tests can pass while an MCP server still breaks at its process boundary. Here is a small Node.js smoke test for the initialize handshake, tool discovery, JSON-RPC calls, and stdout discipline.

Don't let a benchmark decide what "fast enough" means

Decide "how many ms counts as fast" from a benchmark and you will always miss. For subtitle translation the target was a deadline worked backwards from how long the subtitle stays on screen. Speed isn't a continuous value — it's a cliff.


Swahili from 0% to 30%. But the value wasn't the score — it was that the failures changed

Swahili is one of the languages AI is worst at. The base model's accuracy was 0%. Even after instilling the fundamentals, 30%. Far from a pass. But what was worth more than the 30% gain was that the failures themselves changed. Look at the distribution of failures, not the absolute score — how I worked out what was really rate-limiting in a low-resource language.


Let the AI pick a translation better than the "right answer"

"Prepare one correct set of model answers and have the model imitate them" — that's the conventional wisdom in AI training. But have the teacher produce N candidates and let a quality estimator (QE) pick the best, and you get model answers that beat the teacher's first shot — the "next move" I expect the most from in LYR. And what I'm sure of is the flip side: if the yardstick you select with is off target, you lose outright to one clean set of model answers (measured: 82% → 73–77%). Breaking the faith in the one right answer, and honestly measuring both what it buys you and where it stops.
